30, wing structure 12 moves into a configuration that is a mirror image of the configuration at the beginning of flutter shown in Fig. In a preferred embodiment, the invention is an apparatus for extracting power from a moving fluid stream, said apparatus comprising: a mast; a sleeve that pivots about said mast; a wing structure selected from the group consisting of: (1) at least two stand-off arms, each of which stand-off arms having two ends, a first end that is fixed to said sleeve and a second end upon which a hinge is mounted, and a symmetrical airfoil having a forward edge that is attached each said hinge, and (2) a first airfoil portion having two ends, a first end that is fixed to said sleeve and a second end upon which a pivot is mounted, and a second airfoil portion having a forward edge that is attached each said pivot, wherein said airfoil portions are configured to, as a combination, present airfoil surfaces to the moving fluid stream that generate lift first in one direction that is transverse the direction of movement of the moving stream and then in another direction that is opposite said one direction during an oscillation of said airfoil portions in the moving fluid stream; and a power take-off mechanism that comprises a pair of overrunning clutches, a drive shaft that is connected to said pair of overrunning clutches, a gearbox that is connected to said drive shaft and a generator that is connected to said gear box; wherein said wing structure is configured to flutter back and forth in the moving fluid stream which is operative to cause said sleeve to pivot back and forth; and wherein said pivoting movement of said sleeve is converted to rotational movement of said drive shaft in a single direction by means of said pair of overrunning clutches.

Referring to Fig. 26, another preferred embodiment of wing section 12 is illustrated. 1 is an elevation view of a preferred embodiment of the invention. Fig. 9 is a plan view of a superimposition of the images of the four stages of oscillation of the wing structure of a preferred embodiment of the invention.

24H illustrates a 3DL process sail, single element stand-off embodiment. Steps F to G and steps L to A show transition portions of the flapping sequence in which the single body wing structure on a stand-off arm continues its rotation, and the lift direction of the airfoil as a whole reverses. Steps F to G and steps L to A show transition portions of the flapping sequence, in which the trailing edge portion 22 of hinged wing structure 12 continues its rotation and the lift direction of the airfoil as a whole reverses.

For a shape which undergoes an inversion, there are a range of lift forces generated, and it is preferred that the shape offer the most efficient form for lift generation at each point of its half-cycle. The optimization of forces that produce lift is carried out with a shape over which fluid flows smoothly. Theoretical calculations based on preferred embodiments predict that a Wind Fin measuring 20 feet tall by 3 feet wide on a thirty foot mast in a 20 mph wind would generate slightly over IkW of electricity. Fig. 24 A through 24H are elevation views of preferred embodiments of the invention. Figs. 42-45 are plan views that illustrate the steps in the oscillation of a preferred two- element embodiment of the invention. Figs. 26-30 are plan views illustrating a complete oscillation of a preferred embodiment of the invention. Many variations of the invention will occur to those skilled in the art.
